However, human error can limit the accuracy of the measured frequency response functions when the tests are conducted manually, as the FRFs are influenced by the locations and orientation of the hits, as well as the magnitude of the impact if the test piece is nonlinear.

This scenario might arise due to various factors, such as availability of limited number of sensors, partial access to the structure etc. In these circumstances, the task is to patch together the data obtained from various patches so that modal parameters, repres

Reliability of Using Stereo Photogrammetry to Estimate Modal Parameters, few years. In this technique, full-field data can be taken in a single snapshot, which can be considered a great advantage over conventional measurement techniques such as laser vibrometer and accelerometer. However, it is not clear whether the stereophotogrammetry data can provide accurate modal p

The equal mass constraint shows that any increase in performance is due to the addition of the vibration absorbers and not due to adding additional mass to the structure. In this paper, two different metastructure designs ar

Specific about the method is that the well-established statistical concept of maximum likelihood estimation is applied to estimate directly a modal model based on measured Frequency Response Functions (FRFs). Due to the nature of this model, the optimal modal parameters are estimated us
